A mesmerizing new video shows Earth setting behind our moon as a spacecraft flies in the vicinity.
Artemis 1, the first flight of NASA's Artemis program, launched early Wednesday morning (Nov. 16). All milestones after launch atop the huge Space Launch System rocket have been checked off so far, including a crucial engine burn of the uncrewed Orion spacecraft at the moon on Monday (Nov. 21).
NASA carried the engine burn live and also livestreamed footage of Orion flying near the moon when a signal from the capsule was available.
"You are seeing the Earth; you are seeing home. You are seeing yourself in that image right there as Orion is 232,000 miles [373,000 kilometers] away from planet Earth," NASA spokesperson Sandra Jones said during live coverage of the Orion lunar flyby Monday (Nov. 21) on NASA Television.
Orion's high-definition view of Earth on Monday was far from the first time we've glimpsed our planet from so far afield.
During the broadcast, Jones evoked the famed Christmas Eve broadcast from Apollo 8 on Dec. 24, 1968, when three astronauts beamed home live black-and-white footage of the moon, during the first orbital lunar journey by humans. Apollo 8 crewmember Bill Anders also captured a still color image of "Earthrise" above the lunar surface that remains iconic to this day.
Jones also referenced the "pale blue dot" image taken by NASA's Voyager 1 probe in 1990 from above the plane of the solar system and beyond the orbit of Neptune. The moniker came from scientist and science popularizer Carl Sagan.
In recent years, Earth-observing satellites like Suomi NPP and GOES-16 have provided "blue marble" photos from high above our planet. Periodic flybys by spacecraft such as BepiColombo in 2020 also have shown our Earth's full disc.

After Orion's Monday flyby, NASA flight director Zeb Scoville said the view of Earth setting behind the moon "is a game-changer" as NASA prepares to send humans back to lunar realms with the Artemis 2 mission, currently slated to fly no earlier than 2024.
"Going to work at NASA, when I got here we were flying shuttle," Scoville recalled on NASA Television.
"We were building a space station and flying it. That is an incredible vehicle, but on the horizon was always how humanity was going to back to the moon ... [We're] preparing to bring humans back there within a few years. This is a game-changer."
